Criteria Used for Evaluation

Breathability

Breathability and moisture-wicking are essential in keeping your feet healthy and odor-free.

In any activity or situation where your feet are sweating - say, when you’re exercising or if it’s hot outside - there’s a potential of developing a number of unpleasant conditions or diseases. The most harmless of them is probably bad odor, which is produced by microbes that thrive in hot and damp environments, such as in your sweaty footwear.

The more dangerous issue would be an infection, either bacterial or fungal, which could take a while to cure and could set you back in terms of your training and physical fitness levels.

To avoid these problems, breathability is essential. Air needs to be able to freely flow in and out of both your footwear and your wool running socks as this is what cools down your feet and helps combat the sweat.

Fortunately, wool is a pretty breathable material. It promotes air circulation, and this feature is even more enhanced when wool designs have mesh parts built into them. Mesh is a porous fabric that is even more breathable than wool, and together these two make a winning combination in terms of keeping you dry and cool as you run.

When we talk about breathability, we can’t mention moisture-wicking as well, as these two go hand in hand.

Moisture-wicking is the ability of the material to pull droplets of sweat away from your skin and to the outer layers from where it can evaporate. In high-impact sports such as running, having moisture-wicking socksis crucial in maintaining a healthy foot environment.

This is usually achieved through various engineered fabrics and technologies which add moisture control to design. Look for names such as Coolmax (a type of polyester that is moisture-wicking), and systems like Nike’s Dri-FIT or the iWick fibers in Features designs.

We’re not saying that you won’t be able to complete your run without breathability and moisture-wicking, but they will certainly make you more comfortable and improve your performance overall.

Shock Absorption

Choose a level of cushioning you feel the most comfortable with.

While cushioning is mostly provided by your running shoes, it won’t hurt to have a little extra in-store in your wool running socks as well. Cushioning not only provides comfort and a soft, supportive feel underfoot while you run, but it also serves the purpose of protecting your feet, your muscles, and your joints from impact damage.

What exactly is this impact damage?

As you walk, and especially as you run, your feet hit the ground with every new step. This landing, or heel strike as it’s called, generates a certain amount of force or shock that travels from the ground up into your foot and leg. This shock may cause micro-injuries to your joints (ankles, knees and even hips) and muscles which can compound over time, leading to pain and certain foot and leg ailments later on.

In order to reduce the shock that reaches these sensitive areas, sports gear manufacturers add cushioning to their footwear and apparel.

Cushioning can be thicker or thinner, depending on whether or not you favor a more minimalist feel, or if you prefer plenty of bounce on your run. In this type of socks, it can also be concentrated in certain areas, such as the ball and the heel of the foot, or it can be full-length cushioning, all along the bottom of the sole.

We ranked the designs in this guide according to the level of cushioning they provide. At the top of the list are the ones which have the most cushioning, while the ones which have less are at the bottom. Depending on your personal preferences and style of running, make sure to choose which level of cushioning suits you best.

Support

Arch support will keep you going for longer and stave off foot fatigue.

While cushioning is important in protecting you from impact and keeping you comfortable, there’s something to be said about support as well. Support is essential in reducing the strain your feet go through to maintain proper balance, a natural gait and to propel you through your run. It also prevents foot fatigue and is a must-have when you’re spending a lot of time on your feet, or when you’re engaged in serious sports activity.

Similar to cushioning, support is mostly provided by your footwear. However, there is a number of wool socks for running which also offer support that works together with your footwear in helping you give it your all in your next training session.

In this case, support comes in the form of arch compression. One part of a design, the one which goes around your arch and instep, is tighter than the rest, and this provides a bit of compression to the arch area. This compression helps keep your arch elevated and prevents it from falling as your run. It is a great feature to have whether you’re a neutral runner or an overpronator.

Support can also be a deep heel pocket of the sock. Y-stitched heels are something you may have run into in this guide - they provide a special fit around the heel area. This makes the heel sit more comfortably inside the sock and keeps it more secure as you pound the track.

If you’re serious about your running and want to make sure that your potential is maximized, then opt for designs that come with one or more forms of support. It will only improve your performance and keep you going for longer and harder than you ever thought you possibly could.

Fit

The fit of your socks should be snug but not too tight.

In order to make the most out of your new wool running socks, they have to fit properly. A poor fit may mean the difference between a successful run or a new personal best and a workout that is abruptly ended because of blisters or discomfort. There is nothing worse than a sock which is too tight that it hurts us or too loose that we constantly have to pull it up as we go.

Which is the main thing about fit: it needs to be just the right amount of snug, but not too snug. It shouldn’t be leaving dents or marks on your skin, and it definitely shouldn’t be cutting off your blood flow. A lack of circulation will lead to cold feet and potential numbness, and perhaps even worse consequences later down the line.

Equally, your socks shouldn’t be too loose, either. Aside from the fact that they will be slipping down and will be plain annoying, they will also bunch up in your footwear. This excess material will rub against your skin and sooner or later, due to constant movement on your run, it will cause a blister or a hot spot to appear. Needless to say, no one wants that during their training.

This is why it is vital that the fit of the design is just right for you. Options with spandex/elastane/Lycra in them have more stretch than those that don’t, and as such, they are more accommodating to different foot shapes. This material along with nylon ensures that a design fits closely to your foot and that it doesn’t slip or bunch up as you move.

Make sure to consult the brand’s size chart before you decide which size would be the right one for you.

Durability

Durable materials and reinforced heel and toe areas will increase the lifespan of your socks.

Seeing as running is a demanding, high-impact sport, it is only understandable that the gear you use for running is not too long-lived. Depending on the frequency of your runs, their duration, and type (such as what terrain you’re taking on), a good pair of wool socks for running can last you anywhere from a couple of months to a whole season or maybe two.

The harder you go, the more challenging environments you take on and the more often you wear your new socks, the more quickly they will deteriorate. This is just the nature of things, and there is no design from any brand that can circumvent this issue.

However, there are some features you can look for to make sure that you are getting the most durable option for the price you’re paying.

The first of these would be the material type. Wool in itself isn’t very durable and tends to lose shape over time, especially with regular wash cycles. This is why materials such as polyester, acrylic, nylon and other synthetics are added to increase the longevity of these designs. Try to find a good balance between wool and these fabrics.

Additionally, reinforced areas of the design, such as heel and toes, will stop them from thinning out too soon. These parts are the most prone to developing holes, and added strong fibers or layers of material here will make sure that your toes don’t poke through the fabric too soon.

Finally, it is important to emphasize that you shouldn’t hold yourself back from wearing your new favorite socks just because you’re worried they will fall apart. They will do that anyway, sooner or later, and it is important that you make the most of them before that happens.

So throw them on, lace up your running sneakers and hit the track with confidence! If something happens to your socks along the way, you can always opt to buy a new pair, with a different material make-up if you so desire.
